Module transport 

Transport trait — decouples hardware tools from wire protocol.

Enums

TransportError

Transport layer error.

TransportKind

Transport kind discriminator. Used for capability matching — some tools require a specific transport (e.g. pico_flash requires UF2, memory_read prefers SWD).

Traits

Transport

Transport trait — sends commands to a hardware device and receives responses. All implementations MUST use explicit tokio::time::timeout on I/O operations. Callers should never assume success; always handle TransportError.
